定数截尾寿命试验中独立Weibull分布寿命比率的统计推断

Inference of Life Time Ratio for Two Independent Weibull Populations in Type-I Truncated Life Time Experiments

在产品寿命服从Weibull分布的无替换定数截尾寿命场合下,提出了两独立总体的两个平均寿命比率估计量,并研究了它们的偏倚,渐近正态性,区间估计,然后进行了随机数值模拟,进一步验证了所提估计量的有效性.

In this paper,we considered the statistical inference of the life time ratio for two independent populations,which follow different Weibull distribution in no displacement typeI truncated life time experiments.We proposed two estimates for the life time ratio and investigated their theoretical properties.Through data simulation,we illustrated that the proposed esimates can work very well.
